Car-mover



UNITED STATES PATENT OFFICE JOHN SKINNER AND CHARLES B. I/VALLACE, OF FLINT, MICHIGAN.

CARrMOVE R.

SPECIFICATION formifig part of Letters Patent No. 406,240, dated July 2, 1889.

Application filed May 6, 1889. Serial No. 309,738. (No model.)

To to whom it may concern.-

Be it known that we, JOHN SKINNER and OHARLEs 13. WALLACE, citizens of the United States, residing at Flint,in the county of Genesec and State of Michigan, have invented certain new and useful Improvements in Car- Movers, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to new and useful improvements in car-movers; and the invention consists in the peculiar construction of the shoe, wherein a better grip is obtained upon the rail, and, further, in the peculiar arrangement of a spring on the under side of the shoe, which acts to raise the shoe from off the rail and allow it to be moved along with the least possible friction, all as more fully hereinafter described.

In the drawings which accompany this specification, Figure 1 is a vertical central section through our improved car-mover as in use. Fig. 2 is a perspective view of the shoe detached. Fig. 3 is a bottom perspective view of the same, and Fig. 4 is a cross-section on line X X in Fig. 1.

A is the car-wheel.

B is the rail upon which our device is applied. v

The mover is adapted to move cars a short distance upon the tracks by hand-power applied to a compound lever, the power being brought upon the periphery of the wheel.

Our mover consists of the shoe 0, which is constructed of the body a, having a concave lower surface, and flanges I), having apertures c and d for pivots e and 6, upon which the levers D and E are pivotally secured. The

- short lever E is provided with a pivot f at its upper. end and connects the link F with the pivot g in the lever D. The forward end of the lever E is adapted to abut against the flange of the wheel near the track, all so arranged that when the operator depresses the handle of the lever D the forward end of the lever E will be lifted up and press the wheel around and forward, thus moving the car.

In order to get the greatest possible amount of friction between the track and the shoe the latter is at its lower surface concave, as shown, and a square pin h is secured in a suitable aperture through the shoe in such position thatits central part 1' projects through the concave part of the shoe, as shown in Figs. 3 and 4. In the bottom of the shoe a T-shaped recess is formed, adapted to receive a T-shaped spring 70, secured at its rear end in any suitable mannerto the shoe, and of such construction that in its normal position the headl of the spring will be held some distance below the bottom of the shoe. The pivot e is preferably locked in the circular abutment 'm, a corresponding recess 11 being formed in the shoe, and the end of the lever D, through which the pivot e extends, is also enlarged to strengthen the parts, a suitable recess 0 being formed in the shoe.

The parts being thus constructed, they are intended to operate as follows: The device being put in the position shown in Fig. 1, the operator depresses the lever D, raises the forward end of the short lever E, which impinges against the car-wheel and moves the car along. The pin h, by its sharp protruding edge i on the upper surface of the rail, bites into the rail, and prevents the shoe from slipping backward. The operator then lifting upon the handle D, the downward strain is taken from the shoe, and the tension of the spring is lifts it from the rail, except at its forward point, releasing the friction of the concave surface and also the bite of the pin 1', so that it is easily moved along for another hold and another application of power.

This construction makes an easy-working and powerful device, and obviates the necessity of lifting the entire device off the rail each time to move it along, as in other constructions.

What we claim as our invention is 1. In a car-mover, the combination, with the levers pivotally connected to a shoe having the concave bottom, of a spring secured in the under side of the shoe and adapted to raise one end thereof, and of the sharp-edged pin proj ecting with its edge through the shoe, substantially as described.

2. In a car-mover, the combination, with levers pivotally connected to a shoe having a concave bottom, of the sharp-edged pin projeeting with its middle nearly through said shoe, the T-shaped spring normally extending below said shoe, a recess formed in the upper portion of the shoe for the reception of the corresponding portions of the levers and of the flanges I), substantially as described.

In testimony whereof I affix my signature,

in presence of two witnesses, this 8th day of I 5 March, 1889.
